2015-12-17DWARF: handle variable-length records and variant partsPierre-Marie de Rodat14-126/+2067
Enhance the DWARF back-end to emit proper descriptions for variable-length records as well as variant parts in records. In order to achieve this, generate DWARF expressions ("location descriptions" in dwarf2out's parlance) for size and data member location attributes. Also match QUAL_UNION_TYPE data types as variant parts, assuming the formers appear only to implement the latters (which is the case at the moment: only the Ada front-end emits them). Note that very few debuggers can handle these descriptions (GDB does not yet), so in order to ease the the transition enable these only when -fgnat-encodings=minimal. gcc/ada/ChangeLog: * gcc-interface/decl.c (gnat_to_gnu_entity): Disable ___XVS GNAT encodings when -fgnat-encodings=minimal. (components_to_record): Disable ___XVE, ___XVN, ___XVU and ___XVZ GNAT encodings when -fgnat-encodings=minimal. * gcc-interface/utils.c (maybe_pad_type): Disable __XVS GNAT encodings when -fgnat-encodings=minimal. gcc/ChangeLog: * debug.h (struct gcc_debug_hooks): Add a new size_function hook. * debug.c (do_nothing_debug_hooks): Set the size_function field to no-op. * dbxout.c (dbx_debug_hooks, xcoff_debug_hooks): Likewise. * sdbout.c (sdb_debug_hooks): Likewise. * vmsdbgout.c (vmsdbg_debug_hooks): Likewise. * stor-layout.c (finalize_size_functions): Let the debug info back-end know about the implementation of size functions. * dwarf2out.h (dw_discr_list_ref): New typedef.
